Abstract

This research was funded through the American Speech and Hearing Foundation's 2012 StudentResearch Grant in Early Childhood Language Development awarded to Vanessa Harwood as well as an anonymous generous donation to Haskins Laboratories. Electrophysiological measures of language within early childhood provide important information about neurolinguistic development. We investigated associations between amplitude and latency of the P1 and N2 event-related potential components in response to spoken pseudowords, and clinical measures of language performance within a sample of 58 typically developing children between 24 and 48 months. N2 amplitude differences between repeated and new tokens were correlated with measures of expressive and receptive language and speech sound production. Phonemic sensitivity measured by the N2 component may reflect the integrity of neural networks that are important for speech perception and production in young children.

言语事件相关电位与幼儿的语音产生和语言有关。

这项研究是由美国语言和听力基金会2012年儿童早期语言发展学生研究基金资助的，该基金授予Vanessa Harwood，以及哈斯金斯实验室的匿名慷慨捐赠。儿童早期语言的电生理测量提供了神经语言发展的重要信息。我们研究了假话口语反应中P1和N2事件相关电位分量的振幅和潜伏期之间的关系，并对58名24至48个月的正常发育儿童的语言表现进行了临床测量。重复符号和新符号之间的N2振幅差异与表达性和接受性语言和语音产生的测量相关。通过N2分量测量的音素敏感性可能反映了神经网络的完整性，这对幼儿的语言感知和产生很重要。

期刊介绍： Devoted to exploring relationships between brain and behavior across the life span, Developmental Neuropsychology publishes scholarly papers on the appearance and development of behavioral functions, such as language, perception, and social, motivational and cognitive processes as they relate to brain functions and structures. Appropriate subjects include studies of changes in cognitive function—brain structure relationships across a time period, early cognitive behaviors in normal and brain-damaged children, plasticity and recovery of function after early brain damage, the development of complex cognitive and motor skills, and specific and nonspecific disturbances, such as learning disabilities, mental retardation, schizophrenia, stuttering, and developmental aphasia. In the gerontologic areas, relevant subjects include neuropsychological analyses of normal age-related changes in brain and behavioral functions, such as sensory, motor, cognitive, and adaptive abilities; studies of age-related diseases of the nervous system; and recovery of function in later life. Empirical studies, research reviews, case reports, critical commentaries, and book reviews are featured in each issue. By publishing both basic and clinical studies of the developing and aging brain, the journal encourages additional scholarly work that advances understanding of the field of lifespan developmental neuropsychology.
